For example, the reinforcing member 400B may include polyethylene terephthalate (PET).

As a summary and review, a display panel and window components can be vulnerable to external shocks. A portable terminal can be damaged due to impact when the portable terminal is dropped.

The embodiment provides a display device with improved durability and high impact resistance. The embodiment provides a portable terminal with improved durability and high impact resistance.
